Threaded core set

Threaded core versions

The base of the threaded cores form a workpiece which already has a splined shaft profi le. This gives rise to different thread core variants, according to customer demands and technical specifications:

Single-piece threaded core

threaded core workpiece - with spined shaft profile

Single-piece threaded core - without cooling

A

Single-piece threaded - with cooling

B

Single-piece threaded core - as sleeve

C

Threaded core holder + insert

Threaded core holder + insert - without cooling

D

Threaded core holder + insert - with cooling

E

Threaded core holder + 3-part insert - with cooling

F

Threaded core sizes

Servomold threaded cores are available in different dimensions. Depending on thread size and cavitiy distance, various system sizes are used: (ED = external diameter / SP = diameter of splined shaft profile)

Threaded core material

Servomold threaded cores are standardly made of Böhler M340. This high performance plastic mold steel is eminently suitable for threaded cores:

Excellent corrosion resistance properties

Good hardenability (Servomold hardens this steel with 56 ±1 HRC)

High wear resistance
